"From my point of view, I think it's been fairly consistent. The one error that was very costly [in Germany] - that was quite small, because I wasn't even trying but went off.

"That's part of the game. I can't rewind the clock. It has happened. It obviously hurt us, but I'm quite confident that if we have the car to fight with, we can put them under pressure and make things happen in the second half.

"Last year, we lost the championship I think because our car wasn't quick enough to be a match in the final part of the season.

"So I hope that this year, and I think this year has shown so far that our car is more efficient, our car is stronger and still has a lot of potential to unleash.

"I'm quite confident with what's sitting in the pipeline that we can improve. So we'll see. It should be an exciting second part of the year."
